4. Installation

4.1 LocationThe Quest Dual can be installed in a variety of locationstomeettheowner’sneeds;otherconsiderationsinclude:

1. Providing access to a 115 VAC power outlet (10’ power cord is provided).

2.Locatingnearafloororothersuitabledrain (8’ drain hose included).

3. Mount 4” above drain.

4. Do not install the Quest Dual with the exhaust of the unit within 1’ of a wall or obstruction. Do not place the unit near open water.

4.1A No Ducting (fig. 1)The simplest installation is to place the Quest Dual with no ducting. To ensure optimal performance, the air inletandtheoutletoftheunitmustbeatleast2’fromwallsandotherobstructionstoairflow.Recirculationof outlet air into inlet should be avoided as much as possible.

WARNING! Before installing the dehumidifier in the manner described in section 4.1D (Fig. 4), call the factory for specific instructions if backdraft devices (i.e. hot waters heaters) are present in the space to be dehumidified.

WARNING!

4.2 Electrical RequirementsThe Quest Dual plugs into a common grounded outlet on a 110-120 VAC 15-Amp circuit. Use of a ground fault circuit interrupter (GFCI) protected circuit is recommended. The unit should not be used in areas prone toflooding.

CAUTION! For proper drainage, the unit must be mounted so the drain outlet is at least 4” above the floor drain, and must be fully supported under the base.

4.3 Condensate (Water) Removal Condensate drains by gravity via the drain port. Use 3/4” male NPT PVC pipe. Route drain to drain. Install a trap if possible. Take care when installing drain pipe to drain port. Use an adjustable wrench to secure the drain port. An optional condensate pump kit (4028614) may be installed if a lift is required to dispose of the condensate. To order call 1-800-533-7533.

Wheninstallingthedrainhosemakesurethefeetareextendedsuchthatthedehumidifieris21/2”offtheground. Then coil the drain hose under itself or position a spacer to lift the hose 1” off the ground after the hose has touched the ground. This procedure will create a trap that ensures your unit drains correctly. See thediagrambelowforfurthervisualclarification.

5. Ducting 5.1 Supply Duct Kit (P/N 4028607)

A factory designed supply duct kit can be purchased to accept 10” ducting to both outlets of the Quest Dual. Contact your dealer or call 1-800-533-7533 to order.

5.2 Return Duct Kit (P/N 4028610)

A factory designed return duct kit can be purchased to accept 12” ducting. Contact your dealer or call 1-800-533-7533 to order.

6. Operation 6.1 Humidity Control Adjustment

The humidity control is an adjustable switch that closes when the relative humidity of the air in which it is located rises to the dial set point. It opens when the RH drops 4 to 6% below the set point.

Approximate Humidity Levels Per Setting

“Dry” 20% to 30% Relative Humidity

“Normal” 50% Relative Humidity (Recommended)

“Humid” 80% to 90% Relative Humidity

Thedehumidifierwillrununtiltherelativehumidity(RH)isreducedtothehumiditycontroldialsetting.

Quality humidity meters are available from the factory and are recommended to accurately monitor humidity levels. Contact your dealer or call 1-800-533-7533 to order.

6.2 Blower (Fan) Switch

Turning the blower switch to “FAN ON” will cause the unit’s internal blower to run continuously, whether the unit is dehumidifying or not. This function is desirable if the unit is used for air circulation.

Turning the blower switch to “FAN AUTO” will cause the unit’s internal blower to run only while the unit is dehumidifying.

7. Maintenance WARNING! NOTE: Do not operate the unit without the filter or with a less effective

filter. The heat exchange coils inside the unit could become clogged and require disassembly to clean.

8. Service WARNING! Servicing the Quest Dual with its high pressure refrigerant system and

high voltage circuitry presents a health hazard which could result in death, serious bodily injury, and/or property damage. Only qualified service people should service this unit.

8.1 Technical Description

The Quest Dual uses a refrigeration system similar to an air conditioner’s to remove heat and moisture from incoming air, and add heat to the air that is discharged. Hot, high pressure refrigerant gas is routed from the compressor to the condenser coil. The refrigerant is cooled and condensed by giving up its heat to the airthatisabouttobedischargedfromtheunit.Therefrigerantliquidthenpassesthroughafilter/drierandcapillary tubing which cause the refrigerant pressure and temperature to drop. It next enters the evaporator coil where it absorbs heat from the incoming air and evaporates.

Theevaporatoroperatesinafloodedcondition,whichmeansthatalltheevaporatortubescontainliquidrefrigerantduringnormaloperation.Afloodedevaporatorshouldmaintainconstantpressureandtemperature across the entire coil, from inlet to outlet. The mixture of gas and liquid refrigerant enter the accumulator after leaving the evaporator coil. The accumulator prevents any liquid refrigerant from reaching the compressor. The compressor evacuates the cool refrigerant gas from the accumulator and compresses it to a high pressure and temperature gas to repeat the process.

8.2 Troubleshooting

FOR THE END USER:

If the unit does not work properly, please check the following:

— Is the unit unplugged?

— Is power to outlet on? (check switch, if applicable)

— Is circuit breaker tripped?

— Is humidity control set? (turn to “ON”)

—Isairflowrestricted?(checkairfilterandgrill)

If none of the above, call dealer or 1-800-533-7533.

FOR THE HVAC PROFESSIONAL:

No dehumidification. Neither blower, nor compressor run with fan switch AUTO.

1. Unit unplugged or no power to outlet, circuit breaker tripped.

2. Humidity control set to “Humid” setting.

3. Loose connection in internal wiring.

4. Humidity control is defective.

No dehumidification. Compressor does not run but blower runs with fan switch AUTO and humidity control turned to ON.

1. Defrost thermostat open, ambient temperature too low.

2. Loose connection in compressor circuit.

3. Defective compressor overload.

4. Defective compressor or compressor run capacitor.

Blower runs with fan switch AUTO but compressor cycles on & off.

1. Low ambient temperature and/or humidity causing unit to cycle through defrost mode.

2. Defrost thermostat defective.

3. Defective compressor overload.

4. Defective compressor.
